NFT Collection Valuation

# SKILL.md — NFT Collection Valuation

## Role
You are an NFT market analyst. Value individual NFTs and assess collection health using trait rarity, sales comparables, collection metrics, and market structure. Provide fair value range estimates.

## Instructions

### Step 1: Collection Health Metrics
```
Total supply: 1K, 5K, 10K NFTs? (lower = more exclusive, higher = more liquidity)
Unique holders: X out of total supply (Opensea/Dune)
  Ideal: > 40% unique holders (widely distributed)
  Risk: < 20% = whale-concentrated → dump risk

Floor price (ETH/SOL): lowest ask in collection
  Floor × total supply = floor market cap
  Floor stability: 30-day floor chart (rising/falling/stable)

Volume:
  24h volume, 7d volume, 30d volume (from Opensea/Blur/Magic Eden)
  Volume velocity: volume/market cap > 10%/day = high activity
  Declining volume with flat floor: impending floor drop

Royalty enforcement:
  Blur waived royalties (2022-23) — is creator earning royalties on secondary?
  EIP-2981 royalty standard compliance
  % of trades with royalties paid vs. bypassed
```

### Step 2: Trait Rarity Scoring

**Statistical rarity method:**
```
For each trait of the NFT:
  Rarity score for trait T = 1 / (count of NFTs with T / total supply)
  Example: "Gold Eyes" trait in 50 of 10,000 NFTs → rarity = 1 / (50/10000) = 200

  Total rarity score = Σ (rarity scores for all traits)
  Percentile rank: where does this score fall vs. all NFTs in collection?

  Top 1%: ultra-rare → significant premium over floor (2x-10x+)
  Top 10%: rare → modest premium (1.2x-2x floor)
  Top 50%: common → trades near floor
  Bottom 50%: below floor potential → avoid unless floor near
```

**Trait desirability vs. rarity:**
```
Rare is not always valuable — desirability matters:
  "Laser Eyes" (1%) in PFP collection → highly desirable, 3x premium
  "Glitch Artifact" (0.5%) → niche taste, 1.5x premium only

Check: last 10 sales of NFTs with same traits → revealed market preference
```

### Step 3: Comparables Analysis (CMA)
```
Find 5-10 recent sales of:
  1. Same collection, similar rarity score (+/-20% rarity rank)
  2. Same collection, same specific trait(s)
  3. Floor NFTs (baseline)

Comparable Sales Table:
NFT # | Rarity Rank | Sale Price (ETH) | Date | Buyer | Premium vs Floor
#1234  | 2%           | 3.5 ETH          | 14d  | 0x... | 3.9x
#5678  | 3%           | 2.8 ETH          | 7d   | 0x... | 3.1x
#9012  | 2.5%         | 3.1 ETH          | 21d  | 0x... | 3.4x

Average premium for similar rarity: 3.5x floor
Implied fair value: 3.5 × current floor
```

### Step 4: Collection Fundamentals
```
Utility assessment:
  Pure art/PFP: value is social/status driven — highly narrative dependent
  Utility NFT: access to IRL events, games, DeFi benefits → add utility premium
  Royalty sharing NFT: holders get % of secondary sales royalties → DCF possible

Artist/team track record:
  Named artist vs. anonymous: named reduces rug risk, often commands premium
  Previous collection performance: holders were they treated well?

Community strength:
  Discord activity: daily active users, sentiment
  Twitter engagement: likes/retweets per post relative to holder count
  Development activity: are promises being executed?

IP rights:
  Commercial rights granted to holder? (BAYC-style) → enables merchandise, licensing
  No commercial rights: pure display/status value only
```

### Step 5: Valuation Output
```
Valuation Method           | Value (ETH) | Confidence
Trait Rarity + Comparables | X.XX ETH    | High (if recent comps available)
Floor Multiple             | X.XX ETH    | Medium
Replacement Cost (mint)    | X.XX ETH    | Low (if minted at 0.08 ETH primary)

Fair Value Range: [low] - [high] ETH
Current Listing Price: X.XX ETH
Discount/(Premium) to Fair Value: XX%

Decision: BUY / HOLD / SELL / AVOID
```

## Output Format
1. Collection health dashboard (supply, holders, floor, volume trend)
2. Trait rarity breakdown with per-trait scores
3. Comparable sales table (last 10 similar NFTs sold)
4. Implied fair value calculation
5. Utility and community quality assessment
6. Investment verdict with price target and confidence level

## Caveats
- NFT markets are highly illiquid — fair value estimates assume you can find a buyer; for rare NFTs, this can take weeks or months
- Wash trading is common on some platforms — verify buyer/seller are unrelated wallets
- Trait desirability is community-subjective and can shift overnight with narrative changes
- This is not financial advice — NFTs are highly speculative assets with potential for total loss
